Description

Technical Field

[0001] This utility model relates to the technical field of casing inspection, and in particular to a transfer auxiliary device for inspecting an external rotor casing. Background Technology

[0002] As the core load-bearing and protective component of the motor, the outer rotor housing's structural precision, surface quality, and other parameters directly affect the motor's assembly accuracy, operational stability, and service life. In large-scale production scenarios, the outer rotor housing must undergo multiple inspection processes to ensure it meets production standards before proceeding to subsequent assembly stages. The housing transfer process during inspection is a crucial step connecting various inspection stations and ensuring production continuity; its transfer efficiency, stability, and safety directly determine overall production efficiency and inspection accuracy.

[0003] Currently, the transfer process during the inspection of the outer rotor housing mainly relies on traditional transfer equipment, such as simple conveyor belts or robotic arms. However, existing transfer equipment generally suffers from poor adaptability. Due to the unique structure of the outer rotor housing, the clamping mechanisms of traditional transfer equipment struggle to achieve stable clamping of the housing, easily leading to situations such as loose clamping causing the housing to detach or shift. This not only affects the stability of the transfer but may also damage the housing surface due to improper clamping force. Furthermore, the existing transfer equipment has low motion precision, making it difficult to accurately transfer the housing to the designated inspection position within the inspection hood, resulting in positioning deviations, inaccurate inspection results, and low production efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a transfer auxiliary device for inspecting an external rotor housing that can improve overall production efficiency and reduce the risk of damage to the outer surface of the housing.

It is used to output the machine casing after inspection. The transshipment agencies include: The transfer bracket is fixedly installed on the main bracket. The translation frame is fixedly installed on the transfer bracket, and two first slide rails are arranged in parallel on the translation frame; A horizontal sliding plate is horizontally mounted on the translation frame, and the horizontal sliding plate slides in conjunction with the first slide rail. Two second slide rails are vertically mounted on the horizontal slide plate; The lifting carriage is vertically slidably mounted on two second slide rails; The lifting cylinder is fixedly installed on the top of the horizontal slide plate and is used to drive the lifting carriage to slide up and down. The clamping cylinder is fixedly installed on the lifting slide. Three grippers are slidably arranged at the bottom of the clamping cylinder. The clamping cylinder drives the three grippers to slide, inserting the three grippers into the machine housing, and lifting the machine housing by the external support of the three grippers.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Reference Figures 1-4 This embodiment provides a transfer auxiliary device for inspecting an external rotor housing, comprising: The main support 1 is supported on the ground, and the main support 1 is equipped with a detection cover 11 for detecting the machine casing; The transfer mechanism 2 is mounted on the main support 1 and is used for transferring components. The feeding mechanism 3 is mounted on the main support 1 and is used to provide the housing to be tested for the transfer mechanism 2; The unloading conveyor 4 is supported on the ground and connected to the main support 1, and is used to output the machine casing after inspection. Among them, transfer unit 2 includes: The transfer bracket 21 is fixedly installed on the main bracket 1; The translation frame 22 is fixedly installed on the transfer bracket 21, and two first slide rails 23 are arranged in parallel on the translation frame 22; The horizontal slide plate 24 is horizontally slidably mounted on the translation frame 22, and the horizontal slide plate 24 is slidably engaged with the first slide rail 23. Two second slide rails 25 are vertically mounted on the horizontal slide plate 24; The lifting slide 26 is vertically slidably mounted on two second slide rails 25; The lifting cylinder 27 is fixedly installed on the top of the horizontal slide plate 24 and is used to drive the lifting slide 26 to slide up and down. A clamping cylinder 28 is fixedly installed on a lifting slide 26. Three grippers 29 are slidably arranged at the bottom of the clamping cylinder 28. The clamping cylinder 28 drives the three grippers 29 to slide, inserting the three grippers 29 into the machine housing, and lifting the machine housing by the external support of the three grippers 29. In this embodiment, the feeding mechanism 3 transports the outer rotor housing to be inspected to the working range of the transfer mechanism 2, providing the workpiece to be inspected for transfer. In the transfer mechanism 2, the lifting cylinder 27 drives the lifting slide 26 to slide downward along the vertically set second slide rail 25, driving the clamping cylinder 28 and the three grippers 29 at the bottom to approach the housing to be inspected. Then, the clamping cylinder 28 drives the three grippers 29 to slide, so that the grippers are inserted into the hollow structure of the housing, and then the housing is firmly clamped by the external support action of the grippers. After the grippers firmly clamp the housing, the lifting cylinder 27 drives the lifting slide 26 to return to its original position. Then, the horizontal slide plate 24 slides horizontally along the first slide rail 23 on the translation frame 22, accurately transferring the housing to the designated inspection position inside the inspection cover 11 on the main support 1. After the inspection is completed, the horizontal slide plate 24 slides horizontally again, driving the housing to move downward along the first slide rail 25. The casing leaves the inspection cover; the lifting cylinder 27 drives the lifting slide 26 to slide downwards, and the clamping cylinder 28 drives the grippers to retract and release the casing, placing the inspected casing onto the unloading conveyor 4. The unloading conveyor 4 outputs the casing, completing one transfer process. The method of using three grippers inserted into the hollow structure of the casing and then externally supporting it for clamping precisely matches the special hollow annular structure of the outer rotor casing. Compared to traditional clamping mechanisms, this method provides more stable clamping, preventing the casing from falling off or shifting. Simultaneously, the external support clamping avoids the clamping force acting directly on the casing surface, reducing the risk of surface damage. This achieves seamless and coordinated operation of loading, transfer, inspection, and unloading, eliminating the need for manual intervention or secondary transfer adjustments, reducing process redundancy. Furthermore, the stable clamping and precise positioning prevent rework due to workpiece damage or inspection deviations, further improving overall production efficiency.

[0018] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, a rubber outer top block 2a is provided on the outer wall of the gripper 29; In this embodiment, the rubber outer top block 2a has a large coefficient of friction. When it contacts the inner wall of the housing, it generates greater frictional force compared to the gripper 29 directly contacting the inner wall of the housing. This prevents the housing from falling off or shifting during transport, improves transport stability, and ensures that the housing can safely and accurately reach the detection position. The inner wall shape of the outer rotor housing may have certain differences and irregularities. The rubber outer top block 2a has good flexibility and adaptability, and can deform to a certain extent to fit the inner wall of the housing with different shapes, further enhancing the clamping stability. This allows the transport auxiliary device to be applicable to more outer rotor housings of different specifications and shapes. During clamping and transport, the housing may be subjected to certain external forces. The rubber outer top block 2a can play a role in buffering and shock absorption, absorbing and dispersing these external forces, reducing the impact on the housing, and preventing the housing from deforming or being damaged due to excessive external forces, thereby protecting the surface quality of the housing.

[0019] Specifically, such as Figure 2As shown, a travel plate 2b is provided on the side of the lifting slide 26, and a travel switch 2c is provided at the bottom of the horizontal slide 24. The travel plate 2b and the travel switch 2c cooperate to limit the downward travel of the lifting slide 26. In this embodiment, as the lifting carriage 26 descends, when the travel plate 2b descends with the lifting carriage 26 and contacts the travel switch 2c located at the bottom of the horizontal slide plate 24, the travel switch 2c is triggered. The travel switch 2c immediately sends a signal to the control system. Upon receiving the signal, the control system quickly controls the lifting cylinder 27 to stop driving the lifting carriage 26 to continue moving downward, thereby limiting the downward travel of the lifting carriage 26 and preventing it from descending excessively. Through the cooperation of the travel plate 2b and the travel switch 2c, the descent distance of the lifting carriage 26 can be precisely controlled, avoiding excessive compression between the gripper 29 and the housing, thereby effectively protecting the surface quality of the housing. During equipment operation, some unexpected situations may occur, causing the lifting carriage 26 to descend uncontrollably. As a safety protection mechanism, the travel limiting device can play a timely role when the lifting carriage 26 descends beyond the normal range, stopping its descent and preventing safety accidents, thus ensuring the personal safety of the operators and the normal operation of the equipment.

[0020] More specifically, such as Figure 3 As shown, a lifting plate 12 is provided at the bottom of the detection cover 11. The lifting plate 12 is used to support the machine shell to be tested. A lifting cylinder 13 is provided on the main support 1. The lifting cylinder 13 is used to drive the lifting plate 12 to move up and down. In this embodiment, after the housing inspection is completed, the lifting cylinder 13 extends upward, driving the lifting plate 12 to move upward and push the housing out of the inspection cover 11. Then, the gripper 29 of the transfer mechanism is driven by the lifting cylinder 27 to move downward into the inspection cover 11 and insert into the inner cavity of the housing. The housing is then re-clamped by the rubber outer support block 2a. Finally, the transfer mechanism drives the inspected housing out of the inspection cover 11 and transfers it to the unloading conveyor 4 to complete the unloading. The actions of the lifting plate 12 and the lifting cylinder 13 can be precisely coordinated with the transfer mechanism, eliminating the need for manual intervention to adjust the position of the housing, reducing process connection gaps, and improving overall production efficiency.

[0021] Furthermore, a protective rubber pad is provided on the top of the lifting plate 12; In this embodiment, during the process of the lifting plate 12 supporting the machine casing, a certain impact force will be generated between the machine casing and the lifting plate 12 due to the weight of the machine casing itself and the slight vibration that may occur during the transportation process. The protective rubber pad has good elasticity and cushioning performance, which can absorb and disperse the impact force, and prevent the bottom of the machine casing from being damaged due to direct contact with the hard lifting plate 12. This protects the surface quality of the machine casing, reduces the scrap rate caused by surface damage, and improves the overall quality of the product. At the same time, it reduces the noise generated by the collision, creating a relatively quiet working environment in the production workshop, which is beneficial to the physical and mental health of the staff.

[0022] Furthermore, such as Figure 3 As shown, the main support 1 is provided with two guide plates 14, which are located below the lifting plate 12. The bottom end of the lifting plate 12 is provided with two guide bars 15, which slide in cooperation with the two guide plates 14 respectively. In this embodiment, the cooperation of the guide plate 14 and the guide bar 15 provides precise guidance for the lifting and lowering movement of the lifting plate 12. During the lifting and lowering process, the guide bar 15 slides along the preset trajectory of the guide plate 14, which can limit the movement direction of the lifting plate 12, so that it can only perform linear movement in the vertical direction, and avoid the lifting plate 12 from deviating or tilting during the movement, thereby improving the movement accuracy of the lifting plate 12 and ensuring that the lifting plate 12 can accurately support the machine housing to the detection position, thereby improving the accuracy of the detection.

[0023] Furthermore, such as Figure 4 As shown, two component support blocks 16 are arranged in parallel on the main support 1. The component support blocks 16 are used to support the machine casing that has been inspected and transferred. A feeding electric slide block 17 is provided on the main support 1. The feeding electric slide block 17 is located between the two component support blocks 16. A feeding push block 18 is slidably provided at the power output end of the feeding electric slide block 17. The feeding push block 18 is used to push the machine casing onto the feeding conveyor frame 4. In this embodiment, the outer rotor housing, after being inspected by the inspection cover 11, is accurately placed on the placement block 16 by the transfer mechanism 2. At this time, the placement block 16 supports the housing, keeping it stable in the unloading state. After the housing is stably placed on the placement block 16, the unloading electric slide 17 receives a start signal and begins to work. The power device inside the unloading electric slide 17 generates power, driving its power output end to slide, which in turn moves the unloading push block 18. The unloading push block 18 moves along a predetermined straight line towards the unloading conveyor 4. During the movement, the unloading push block 18 contacts the housing and applies a pushing force to the housing, smoothly pushing the housing from the placement block 16 to the unloading conveyor 4. This structure automates the unloading process, eliminating the need for manual handling of the inspected housing from the inspection position to the unloading conveyor 4, thus shortening the unloading time and improving overall production efficiency.

[0024] Furthermore, such as Figure 4 As shown, a guide strip is provided on the component support block 16; In this embodiment, during the process of placing the housing onto the placement block 16, the guide strip can restrict the direction of movement of the housing, preventing the housing from shifting or shaking due to impact or inertia at the moment of placement. The housing can fall onto the placement block 16 quickly and stably, improving the stability of material feeding.

[0025] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
